RTB Posted March 25, 2015 Report Share Posted March 25, 2015 I saw mike's write up and diagram for the IR switch and regulator delete. However, I have an issue. Only 2 of the wire that are in my harness go anywhere, the white/blue and white/red. The other 4 wires go off to another connector. So I am not sure what wires I should be jumping. I will provide photos soon. Quote Link to comment
ggzilla Posted March 25, 2015 Report Share Posted March 25, 2015 Which car model & year are you talking about? 1 Quote Link to comment
RTB Posted March 25, 2015 Author Report Share Posted March 25, 2015 I guess that would be good to specify! The car is a 1970 510. I am not sure which year the engine harness is from but it is a manual harness. Quote Link to comment
ggzilla Posted March 25, 2015 Report Share Posted March 25, 2015 When you unplug the external voltage regulator and throw it away, you'll be left with a six-wire connector. Jump two pairs of those wires. If the old externally-regulated alternator was working before, it doesn't matter if some other connector exists. It may be for choke relay which is tied into the regulator wiring. It is not required to be plugged in. Quote Link to comment
RTB Posted March 25, 2015 Author Report Share Posted March 25, 2015 This is the VR plug. The other wires leading from it just go to a 4 pin plug. These are the wire that connect to the alternator and other various things. One wire in there goes to oil pressure sensor. The black/yellow wire I thought was for auto only so I have no clue what its for. Quote Link to comment
ggzilla Posted March 25, 2015 Report Share Posted March 25, 2015 Doesn't matter for converting from external regulator to IR alternator. Are you trying to ID all the connectors? Or trying to determine if the harness has been modified already? Quote Link to comment
datzenmike Posted March 26, 2015 Report Share Posted March 26, 2015 This is the VR plug. The other wires leading from it just go to a 4 pin plug. Trim the wires on the voltage regulator as long as you can. Poke out the ones not needed. Separate these two pairs... White/Red stripe and White/Black stripe.... and ... solid White and solid Yellow.... Solder the two pairs together and seal with heat shrink tubing. No just plug the voltage regulator plug into your engine harness. No spare wires to touch anything. Quote Link to comment
RTB Posted March 26, 2015 Author Report Share Posted March 26, 2015 So which wire should I be jumping to the alternator mike? Is there a way to remove the plug completely? Quote Link to comment
Just Joel Posted March 26, 2015 Report Share Posted March 26, 2015 Is there a way to remove the plug completely? ;) 2 Quote Link to comment
RTB Posted March 26, 2015 Author Report Share Posted March 26, 2015 I think I'm starting to figure it out, my harness is really strange in that area. Like it doesn't have a T connector or anything. Like the 4 pin plug is supposed to go to the alternator I guess? Quote Link to comment
ggzilla Posted March 26, 2015 Report Share Posted March 26, 2015 Sounds like you need a new harness. 1966-1967 Datsun alternators had a 4-terminal connector, although otherwise identical. so maybe someone in the past did a swap Quote Link to comment
RTB Posted March 26, 2015 Author Report Share Posted March 26, 2015 Maybe. I have some auto engine harnesses but this one was a manual so I figured I would have to do less deleting on this one. I've figured out how to wire it up thanks to Mike and Joel. Now I'm trying to figure out the dash to engine connection. I have an extra 6 pin connection, but that should be the one that goes to the auto relay so it can be tucked up to do nothing. The other is is a 3 pin connector that is green/yellow, white/green, and blue/black and I have no connection for it. Likewise, I have a lone extra wire on the engine side that is white/green. So it will be an interesting puzzle to say the least, unless I just take an auto harness and start deleting stuff. Quote Link to comment
banzai510(hainz) Posted March 26, 2015 Report Share Posted March 26, 2015 take photos really early datsuns had a 4 pin at the alternator. the write up you should just jumper at where the volt reg plugs in(SIMPLE). If to complecated then just run what you have. drawing has been on here for years print it out Quote Link to comment
